ERROR SIGNS
1.
When the induction cooker is in standby or working mode and
the IGBT sensor (NTC1) is open circuit, the display will read E,
the timer display will read E7, and the buzzer will make four
long and five short beep prompts every 5 seconds.
2.
When the induction cooker is in standby or working mode and
IGBT sensor (NTC1) is on a short circuit, the display will read
E, the timer display will read E8, and the buzzer will make four
long, and four short beep prompts every 5 seconds.
3.
When the induction cooker is in standby or working mode and
the NTC2 is on an open circuit, the power display will show E,
the timer display will read E9, and the buzzer will make three
long and five short beep prompts every 5 seconds.
4.
When the induction cooker is in standby or working mode and
NTC2 is on short circuit, the power display will read E, the timer
display will read E2, and the buzzer will give out three long and
four short beep prompts every 5 seconds.
5.
Abnormalities when cooking:
Active cooking zones will not heat up unless we use induction
cooker-compatible cookware.If the system is in working mode’ with
set a temperature, but
• No cookware is placed on the zone.
• The bottom diameter of the cooker is less than 60 mm.
• The cookware is deformed.
• The Floating height is high.
The heating will stop, the power display will read E, the timer display
will read E1, and if it is not recovered within 60 seconds, it will
automatically turn off.
6.
The input voltage is too high
: When the induction cooker is in
working mode, and the voltage is >270V±5V, the heating will
be suspended immediately, the power display will read E, and
the timer display read show E3. If the voltage is <260V±5V for
more than 1 second, the operation will resume automatically.
If the voltage is ≥260V±5V within 10 seconds, the buzzer
will make two long and four short beeps prompts every 5
seconds. The alarm will shut off after 90 seconds or once the
microcrystalline plate’s temperature is lower than 60
℃
.
7.
Input voltage is too low:
When the induction cooker is in
working mode, and the voltage is ≤ 160V ± 5V, heating will
be suspended immediately, power display will read E, the
timer display will show E2 and if the voltage is ≥ 170V ± 5V for
more than 1 second, it will automatically resume working if
the voltage is < 170V± 5V within 10 seconds, and the buzzer
will give out two long and three short beep prompts every 5
seconds. The alarm will shut off after 90 seconds or once the
microcrystalline plate’s temperature is lower than 60
℃
.
8.
IGBT Over-temperature:
If the IGBT temperature is too high,
the heating will stop immediately, the power display will read
E the timer display will read E0, and the buzzer will make four
long and three short beep prompts every 5 seconds. Then
change to the shutdown stroke, and the warning beep will
stop.
9.
Lightning surge voltage protection:
When the induction
cooker is heated, use a standard lightning surge generator,
apply 1.2/50 μs lightning surge voltage of 1200V, and test at
any phase for 10 minutes continuously, the induction cooker
can be heated normally, and the circuit is not damaged.
10. Anti-interference performance:
when the induction cooker
is working, it is subject to 1500V interference of fast electrical
transient - burst (IEC6100-4-4-2004), and the induction cooker
can be heated normally without crashing, shutdown, reset and
circuit damage.
11. Overcurrent protection:
When the working current exceeds
the set value, the circuit will automatically adjust, and the
constant input current will be within the safe range. When the
main circuit is of short circuit and over current occurs, the fuse
will be used for fuse protection.
